Multivariate analysis of factors modulating circulating RBP4 levels

	β	P-value
NASH	0.067	0.529
BMI	0.202	0.063
Age	0.004	0.966
Gender	0.206	0.042
DM or IGF	−0.048	0.633
PNPLA3 genotype	−0.250	0.009

Data were analyzed using linear regression analysis under a recessive model and after adjusting for confounding factors. Values were log transformed before entering the model if not normally distributed.

RBP4, retinol-binding protein 4; NASH, non-alcoholic steatohepatitis; BMI, body mass index; DM, diabetes mellitus; IFG, impaired fasting glucose; PNPLA3, patatin-like phospholipase domain-containing protein 3.
